Blood Health

As part of your full blood count, you will receive a breakdown of the following components of your blood:

Haemoglobin (Hb)

Haemoglobin is a protein which helps transport oxygen to your organs through your bloodstream. It also gives red blood cells their colour.


Platelets are cell fragments in your blood which help blood to clot. They are made in our bone marrow along with red and white blood cells, and are also known as thrombocytes.

Mean Cell Volume (MCV)

Mean Cell Volume (MCV) is a measure of the average volume of a single red blood cell. MCV results are sometimes abnormal in cases of iron or vitamin B12 deficiency.

Mean Cell Haemoglobin (MCH)

Mean Cell Haemoglobin (MCH) is the average amount of haemoglobin in one of your red blood cells. Like MCV, MCH results are sometimes abnormal in case of vitamin or iron deficiency.

Mean Cell Haemoglobin Concentration (MCHC)

Mean Cell Haemoglobin Concentration (MCHC) is a measure of the average concentration (%) of haemoglobin within a single red blood cell. It can be helpful in determining the cause of any anaemia if the haemoglobin is low.

Red Blood Cells (RBC)

Your red blood cell count (RBC), also known as an erythrocyte count, measures how many red blood cells you have. Red blood cells contain haemoglobin, which carries oxygen to your body’s tissues.

Haematocrit (HTC)

Haematocrit (HTC) is a measure of the proportion of your blood which is made up of red blood cells. The Haematocrit reading rises when the number of red blood cells increases or when the blood volume is reduced, for example if you are dehydrated. The reading can decrease when the body decreases its production of red blood cells, which can indicate anaemia.
